SM490 Cov Khoom Siv Carbon Steel Universal H-Shaped Hlau

SM490 Cov Hlau Roj Hlau H nqaj tau faib ua cov hlau tsis muaj carbon, uas muaj lub zog muaj zog dua thiab tawv dua li cov SS400.

SM490 Cov Khoom Siv Hluav Taws Xob Dav Hlau Dav Hlau yog cov khoom lag luam zoo ntawm Japanese (JIS) G3106 thiab yog dav siv hauv kev tsim kho, engineering thiab kev siv khoom siv.

Raws li JIS G3106, muaj peb ntu ntawm SM490A, SM490B thiab SM490C, cov khoom siv me ntsis kom haum rau ib puag ncig sib txawv thiab cov kev xav tau. Tsis tas li ntawd, SM490YA thiab SM490YB yog cov txiaj ntsig zoo ntau yam sib txawv uas muab kev ua tau zoo dua rau cov qauv xav tau.

SM490 H-Beams yog tsim kev siv cov txheej txheem kub kub uas yog cov hluav taws xob kub kom sov thiab tom qab ntawd dhau los ua tus yam ntxwv H-puab. Tus txheej txheem no ua kom muaj kev sib cav sib luag, tshem tawm sab hauv kev ntxhov siab, thiab txhim kho cov hlau cov khoom siv neeg. Tom qab dov, cov nqaj tuaj yeem yog cov npoo npoo, xws li tua peenate lossis cov txheej txheem ua haujlwm, txhawm rau txhim kho corrosion tsis kam thiab txheej.

SM490 H-Cis muab los ntawm GNEE muaj nyob rau ntau qhov ntau thiab tsawg uas ua raws li cov qauv H-Beach Propiles. Qhov loj me yog txhais raws li:
Qhov siab (h): qhov tob ntawm cov nqaj, feem ntau yog xws li 100 mm rau 1000 mm lossis ntau dua.
Flarh Dav (B): Qhov dav ntawm cov Flange, feem ntau yog ib txwm muaj los ntawm 50 hli rau 400 hli.
Web Thickness (Tw): Cov tuab ntawm lub vev xaib ntsug, xws li ntawm 5 hli rau 20 hli lossis ntau dua.
Flange thickness (TF): cov tuab ntawm kab rov tav flange, ib puag ncig ntawm 8 hli rau 40 hli lossis ntau dua.
Ntev: Tus Qauv Ntev yog feem ntau 6m, 9m lossis 12m, GNEE tuaj yeem muab kev cai ntev nyob ntawm cov phiaj xwm kev cai.

Kev sib piv nrog lwm qib

Vs. Tuss400: SM490 muaj ntau dua cov txiaj ntsig thiab lub zog tensile dua li SS400 (245 mpa kom muaj zog), ua rau nws haum rau cov ntawv thov ntau dua.

Vs. ASTM A36: Thaum zoo sib xws hauv lub zog, SM490 muaj qhov zoo dua Weldability thiab yog qhov zoo rau cov qauv welded hauv JIS cov qauv.

Vs. S355: Cov keeb kwm S355 tau sib piv rau lub zog tab sis txawv rau cov tshuaj muaj tshuaj lom thiab cov qauv hauv cheeb tsam.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
